As the San Francisco Chronicle‘s urban design critic for the last decade, John King is one of the Bay Area’s most influential champions of good architecture. He chronicles the city’s projects, both large and small, with an eye to how they how they affect the city. (Most recently, he sounded the alarm about how the America’s Cup, with its proposed yacht dock, could change the waterfront for the worse.) His new book of short essays, Cityscapes (Heyday, 2011, $14.95), is based on his weekly column of the same name.
